More to come for sure (including cast iron d-ports)

In many ways, thermal rejection is more important on a street engine verses a race engine. .125 is one heck of a lot of material when you start to consider aluminum’s inate nature to expand and contract more rapidly than cast iron. A thin deck surface COULD lead to deck cracking, deck warping and head gasket sealing problems as Mike has already pointed out. BTW....before the flaming begins, my comments are based on my experience as an automotive machinist.
